What a lazy bunch we are. According to a survey commissioned by Sport England, half of the population do no exercise at all. Even worse, only one in five of us manage the recommended three sessions of 30 minutes a week. Roll on the Olympics.

The usual refrain is that technology is to blame. But here come's Nintendo's latest console Wii, launched today, which combines movement with computer gaming. The controller is swung, jabbed and waved, acting as everything from a samurai sword to a tennis racket. Playing the console can be such a workout, however, that there have been numerous reports of Wii-related sporting injuries from the US. People who don't warm up properly even run the risk of "Wii elbow".

Could this mix of exercise and flashing graphics to be the answer to Britain's activity apathy, or should we all just get out more?
